prior to dosing day. They must be using an acceptable form of contraception.
B. For female of childbearing potential, acceptable forms of contraception include the following:
i. Non hormonal intrauterine device in place for at least 3 months prior to the start of the study and remaining in place during the study period, or
ii. Barrier methods containing or used in conjunction with a spermicidal agent, or
iii. Surgical sterilization or
iv. Practicing sexual abstinence throughout the course of the study.
C. Female will not be considered of childbearing potential if one of the following is reported and documented on the medical history:
i. Postmenopausal with spontaneous amenorrhea for at least one year, or
ii. Bilateral oophorectomy with or without a hysterectomy and an absence of bleeding for at least 6 months, or
iii. Total hysterectomy and an absence of bleeding for at least 3 months.
3) BMI: 18.5 to 30.0 kg/m2, both inclusive; BMI value should be rounded off to one significant digit after decimal point (e.g. 30.04 rounds down to 30.0, while 18.45 rounds up to 18.5).
4) Able to communicate effectively with study personnel.
5) Willing to provide written informed consent to participate in the study.
6) All volunteers must be judged by the principal or sub-investigator or physician as normal and healthy during a pre-study safety assessment performed within 28 days of study medication which will include:
a) A physical examination (clinical examination) with no clinically significant finding.
b) Results within normal limits or clinically non-significant for the following tests:
Hematology - Hemoglobin, Total RBC count, Total WBC count, Platelet count, Differential leukocyte count and HCT
Biochemistry - BUN, Serum creatinine, Random glucose, SGPT & SGOT, Alkaline phosphatase, Uric acid, Serum bilirubin, Total proteins, Albumin & Serum electrolytes
Urinalysis - Color, quantity, specific gravity, odour, appearance, reaction, albumin, bilirubin,
ketone bodies, sugar, urobilinogen and microscopical examination (performed based
on clinical judgment)
Immunological Tests - HIV-I & II, HbsAg, Syphilis (RPR), Anti HCV & Serum (β-HCG) pregnancy test (for female of child bearing potential)
- Additional tests and/or examinations (apart from mentioned in protocol) may be performed, if necessary, based on principal investigator discretion.
- All results will be assessed against the current laboratory normal ranges at the time of testing and a copy of the normal ranges used will be included in the study documentation.
1) History of allergic responses to Nor-ursodeoxycholic acid, ursodeoxycholic acid or
other related drugs, or any of its formulation ingredients.
2) Have significant diseases or clinically significant abnormal findings during screening
[medical history, physical examination (clinical examination), laboratory evaluations, abdominal ultrasonography recordings, ECG, chest X-ray recording, gynecological history and examination (including pelvic examination and routine breast examination) (for female volunteers)].
3) Any disease or condition like diabetes, psychosis or others, which might compromise
the haemopoietic, gastrointestinal, renal, hepatic, cardiovascular, respiratory, central

half-life of the administered drug prior to the housing.
14) Volunteers who have donated blood or loss of blood 50 ml to 100 ml within 30 days or 101 ml to 200 ml within 60 days or >200 ml within 90 days (excluding volume drawn at screening for this study) prior to dosing of study medication, whichever is greater.
15) History of difficulty in swallowing or of any gastrointestinal disease, which could affect drug absorption.
16) Intolerance to venipuncture
17) Any food allergy, intolerance, restriction or special diet that, in the opinion of the principal investigator or sub-investigator, could contraindicate the volunteerâ??s participation in this study.
